“The mood was very upbeat, it was more like a fun Vanity Fair Oscars party than a memorial," a source reportedly told the site of the service. "All of the speeches were fun and full of life. It was just the way Alan would have wanted it, more of a celebration of his life. Everyone was expressing how much they love him.”

A family member posted photos from the memorial to a public Facebook page, according to E! News, along with a caption that reads, “Tonight’s memorial for Alan was just about perfect. So much family and so many historic friends came out to remember our beloved father-figure. Speaking for Alan so beautifully was (I’m realizing now) an all-star cast.”

The post continued, naming several stars who paid tribute to Thicke throughout the night: "We heard from our own Robin Thicke who brought up all dear dad's best friends, Bob Saget, Bill Maher, Alex Trebec [sic] who I had no idea had such old deep ties to our family, the entire cast of Growing Pains including Leo and Kirk Cameron who I had the pleasure of meeting for the first time, along with his wife who became an instant friend."

There's been a significant outpouring of support from Hollywood since Thicke's untimely death last Tuesday, as celebrities like Demi Lovato, Ellen DeGeneres and more have posted remembrances of the beloved actor all across social media.
